Yet another DSO138 case

Another DSO 138 oscilloscope case design, minimum parts required, easy to print.
Just make sure your printer is calibrated to make exact size as model (mine require 100.7% x-y-scaling).

Vertical printings makes better surface and you don't have to print buttons.
Carefully insert board in (diagonally, see photo), push it up with help of some thin tool and lock.

p.s. Covers with 9V or 6x AAA batteries will be in V2 :-)
